The production of cheap energy-rich and high-protein feed is possible due to the introduction of new types of feed crops. The use of new perennial low-growing crops based on the agrocenoses will make it possible to obtain cheap energy-saturated and high-protein feeds. In addition to the selection and introduction of new species of forage grasses, it is also necessary to evaluate their biological effectiveness in joint and mixed crops. A technique is proposed for assessing the biological activity and relative productivity of mixed and combined three-component crops. Formulas for calculating the land equivalents ratio (LER) and competitiveness coefficients (CR) in three-component mixtures are given. The proposed methodology is based on methods for assessing two-component mixed crops. According to the proposed method, the calculations of LER and CR of three-component joint and mixed crops of legumes, cereals and cruciferous herbs were carried out.
